VEHICLE-AXLE NUT.

SPECIFICATION forming part of Letters Patent No. 639,032, dated December12, 11899'.

Application filed October 2, 1899. Serial No. 732,334. (No model.)

To all whom it may concern,.-

Beit known that I, HARRY R. IIAMER, a citizen of the United States,residing at North Adams, in the county of Berkshire and State ofMassachusetts, have invented new and useful Improvements in Vehicle-AxleNuts, of which the following is a specification.

My invention relates to improvements in vehicle-axle nuts. It providesfor com pensating or taking up looseness and Wear of the axle andaxle-box, thus preserving the proper relation and Working of the parts,preventing oscillations, and obviating premature discarding or frequentrepairing of said parts, and for otherwise promoting` utility,convenience, and facility in use.

My invention consists of an annulus or collar extension for the nut,either integral with the nut or separate therefrom, and in details ofconstruction and arrangement of the parts, substantially as hereinaftermore fully disclosed, and specifically pointed out by the claim.

In the accompanying drawings, embodying the preferred form ofmyinvention, Figure l is a sectional view showing the parts assembled.Fig. 2 is a detail view of the annulus or collar. Fig. 3 is a front viewof the same. Fig. 4 is a viewr of the washer.

In carrying out my invention I employ,n connection with an ordinaryvehicle-axle nut l, an annulus or collar 2, adapted to form an inwardextension thereof to compensate or take up wear of the axle andaxle-box.

The annulus or collar 2 consists of two parts, as it Were, one part 2abeing of a diameter to adapt it to t within or interiorly of the annularflange of the nut 1 to enable the collar or annulus to form an extensionon said nut. The other part 2b of said collar or annulus, of a greaterinterior diameter than the aforesaid part 2a, coincides substantiallywith the flange of said nut, thus providing therefor or taking its placein fitting said collar extension upon the axle, as in app1y-V ing thesame Where the axle or axle-box is Worn or become loose, to maintain theproper Working relation of the parts, prevent oscillations, and obviatethe premature discarding or frequent repairing of said parts. The collarextension 2, thus generally formed, has a radial or circumferentialflange 3, adapted to rest or abut against the circular or annular flangeof the nut 1, and the part 2b of said collar extension has a shoulder 4Cat its base to limit the insertion therein of separate rings, one ofwhich, 5, being shoWn,When employed, or it may be desired to employsuch, to further provide for compensating or taking up wear or loosenessto the last degree. These rings may be of different thicknesses to meetthe emergencies of the case, according to the amount of wear to becompensated.

A spline 6 may be formed on the nut to engage a feather 7 on the flange2,

Having thus fully described my invention, what I claim is- Avehicle-axle having its outer end threaded and a shoulder or enlargementat the termination of the threads, a cap nut fitting the threaded end ofthe axle and bearing against the enlargement, a take-up collar orannular extension having a flange which fits over the enlargement on theaxle and a flange of greaterinteriordiameter to lit within the hub, aflange on the cap-nut fitting over the flange of the take-up which fitsthe enlargement on the axle, and a ring or metal washer tted between thehub and the take-up, substantially as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing Witnesses.

HARRY R. I-IAMER.
